How to become a famous artist, part 2

I have been thinking about it, and here is my opinion about how someone becomes a famous artist.

The person has a simple, understandable, new, unique concept that appeals to a large number of people, and he has a decent level of technical skill.

The person begins making a number of artworks.

The person catches the eye of someone in the art world.

The art world figure validates the artist and introduces him to the world.

Because the art has a broad basic appeal and is easy to "get into", many of the people who encounter it like it.

Soon the artist is famous.

Examples: Andy Warhol, Jackson Pollock, Mark Rothko
